Description
Technical field
The present invention relates to a kind of methods for electric arc line-material coating.In addition, the present invention relates to one kind to be used for electric arc silk material
The equipment of spraying.The invention relates to a kind of products of electric arc line-material coating.
Background technique
Electric arc silk material spraying technology is related to the electric arc conduct by means of generating between the metal wire material that is continuously fed at two
Heat source melts metal, with compressed air is atomized molten metal, and the metallic particles of atomization is made to spray to workpiece and form painting
The technology of layer.The technology by the crankcase of application internal combustion engine of motor vehicle, makes metallic particles shape on cylinder bearing face now
Straticulation.The friction and wear in internal combustion engine is reduced thus significantly, and reaches saving sky by saving traditional cylinder jacket
Between and weight technical effect, and the heat in export combustion chamber is more conducive to relative to cylinder jacket, to be conducive to efficient
It is cooling.
In existing electric arc silk material spraying technology, especially in spraying cylindrical cavity inner surface, the cylinder of such as crankcase
The entire equipment for electric arc line-material coating is usually required in the case where working face to rotate in cylindrical cavity so as in its inner circumferential
Upper formation coating.However, disadvantageously to this, the device for conveying silk material is needed to rotate together with, and thus will generate multiple
Miscellaneous and bulky structure.As shown in 198 41 617 A1 of DE, for conveying the device for supplying of coating silk material and carrying out electricity
The burner bar of arc spraying is rotatably arranged on supporting arrangement, and the device for supplying rotates together with burner bar, wherein
It also needs that silk material capstan winch is arranged in device for supplying.In that publication, since the space for accommodating silk material capstan winch is limited,
It is also required to replace silk material capstan winch often in process of production, it is difficult to continuously be sprayed for a long time.
However, being sent out in the device and method that silk material conveying device is not rotated together with air-flow loading device by research
It is existing, the non-uniform phenomenon of coating can be generated when the inner surface of cylindrical cavity is sprayed, also that is, coating inner edge is not round
, but to a certain extent close to ellipse.In other words, thickness of the coating in the inner circumferential of cylindrical cavity exists
Difference: there are positions thicker at relatively thin position and two at two, wherein the line phase of the line of relatively thin position and thicker position
It is mutually vertical.By manufacturing the experiment of cylinder bearing face with electric arc line-material coating it is found that between most thin position and most thick position
Diameter difference is in 0.2mm between 0.3mm.Such tolerance can all cause nothing in Honing process or even internal combustion engine operation later
The problem of method is ignored.
In cylinder bearing face of such coating as the crankcase of internal combustion engine of motor vehicle, will there arises a problem that.
Firstly, the thicker position of coating is unfavorable for exporting the heat in combustion chamber.This causes that part occurs in the crankcase
Overheat, is unfavorable for the operation of internal combustion engine.In general, visible due to becoming caused by overheating in the thicker position of electric arc silk material coating
It is blue.
Secondly, hole nest (pore nest) can be generated in the coating at relatively thin position, and the coating at thicker position is passing through
Going through then can even occur coating shedding after Honing process.In the present invention, the hole nest refers to the metallic particles being sprayed-on in circle
Not formed compact texture on the inner surface of column cavity, but there is several holes porous structure in other words therebetween.Such hole
Nest will lead to local corrosion aggravation in the operation of internal combustion engine, be unfavorable for the service life of internal combustion engine.In addition, hole nest can also hinder part
Heat transmitting, be unfavorable for heat derives and cooling herein.The coating shedding refers to the coating of the small area quilt in honing process
It peels off, corresponding areas sag or even missing in former coating.Coating shedding occurs in Honing process can then to directly result in
Workpiece is scrapped, because entire coating is difficult to remove.The cost that this point will will cause for producing in enormous quantities improves and material wave
Take.
In addition, uneven thickness will also result in coating stress unevenness.When this is discharged in internal combustion engine operational process, it can cause
The further plastic deformation of coating.And when these deformation reache a certain level, internal combustion engine operation performance or even breaking-up can be damaged
Entire coating.
Finally, due to which coating layer thickness is uneven, need to detect thickness distribution in advance in next Honing process, so as to true
The honing removal amount of fixed each position.Due to needing to remove more coating material in thicker position, hone is exacerbated
Consumption so that the hone lost of life, so that processing cost is high.And it is also required to monitor in real time in honing process.
This undoubtedly causes the waste on time cost again.
